Windows CE and System font

12-Mar-02 23:04

It's not *that* bad. And there should be a plenty of samples with full source code.

AFAIK, there's no info on ObjectiveGrid on CP. You may consider switching to this free grid by Chris Maunder:

Hi out there,

I'm working an instrument based on the Windows CE operating system. The applications is now to be translated into Japanese.
I have found a true type font "MS Gothic.ttf" that supports Japanese charactes. That works fine except for titles in dialogs that use the sysytem font.
I don't want to link the font into the OS image but instead load a system font dynamically.

I have tried to modify the registry:
[HKEY_LOCAL_MACHINE\SYSTEM\GDI\SYSFNT\Nm] from Tahoma to MS Gothic
[HKEY_LOCAL_MACHINE\SYSTEM\GWE\Menu\BarFnt\Nm] from Tahoma to MS Gothic
[HKEY_LOCAL_MACHINE\SYSTEM\GWE\Menu\PopFnt\Nm] from Tahoma to MS Gothic
[HKEY_LOCAL_MACHINE\SYSTEM\GWE\OOMFnt\Nm] from Tahoma to MS Gothic

But it doesn't work.

Any ideas??

How to get highlighted text by double click?

Hello,
I have a problem with text selection. I want to get the highlighted text that users double click on it (not only in my own application). Do I have to use COleDataObject to implement this? Is this about clipboard?

I'm a beginner. Guide me, please. Blush | :O

Yes, it's about clipboard. This code places the contents of strClipboardText variable in clipboad. You'll probably use CEdit::GetSel and CEdit::GetSel and CEdit::GetWindowText to get this string.

CString strClipboardText = ...;

if (!OpenClipboard() || !EmptyClipboard())
{
	AfxMessageBox("Error: can't open the clipboard.");
	return;
}
HGLOBAL hglbText = GlobalAlloc(GMEM_MOVEABLE, 1 + strClipboardText.GetLength()); 
char *pData = (char *)GlobalLock(hglbText); 
lstrcpy(pData, strClipboardText);
GlobalUnlock(hglbText); 
SetClipboardData(CF_TEXT, hglbText);
CloseClipboard();

Assuming that you're using CEdit control, there will be a problem with double-clicking - this action highlights the *word* you're clicking on. Previous selection is lost. You may try to override WM_LBUTTONDBLCLK to change this behavior.

Thank you very much.

But there's a problem. I didn't get highlighted text from edit box but i want to get highlighted text from anywhere on screen (ex. in browser, spreadsheet, notepad, etc.). How can I get it? Guide me, please.

CListCtrl -Max Visible text length 260?

12-Mar-02 18:45

When a string which contains more than 260 characters is inserted in a CListCtrl only the first 260 characters are visible. The string is not truncated cause GetItemText returns the hole string. Any ideas how to show the hole string in the CListCtrl?

Try to custom-draw the control. There should be some articles about that in the listctrl section of CP.

hi,
I’m trying to write a plugin or anything else that will do the job to allow me to put an icon onto Internet Explorer and add some functionality to this icon.
Does anybody know how this can be done?

CEvent Syncronization Class!

12-Mar-02 19:36

Line for line I can't help you, but there are examples of what I think you are looking for here at CP, the greatest place on earth (virtual anyways).

Do a search for IE Toolbar.

I am making a multithreaded app that connects to a serial port and already lots of people here have been a great help!

At the moment I have several threads, two in particular (which coincidentally I have put in a seperate dll) are called RxThread and TxThread, obviously controlling the transmission and receiving of data from the serial port.

What I am trying to do is have a CEvent that I can signal with the RxThread when I have received a reply from a message sent using TxThread (to serial). I know in TxThread I want to WaitForSingleObject for a little while, and if timedout check for messages to TxThread (ie WM_QUIT, not serial messages) and Retry sending (to Serial)!

The trouble is I'm not sure how to create the CEvent object so that I can set it with the RxThread each time I get a reply, and wait for it in TxThread so I can block the thread for a little while!

Thanks for any help
-Mark

Option 1. The RxThread and TxThread belongs to the same process:
- create unnamed CEvent object;
- create RxThread object and pass the reference to the unnamed CEvent object;
- create TxThread object and pass the reference to the unnamed CEvent object;

Option 2: The RxThread and TxThread belongs to different processes:
Both threads must create named CEvent class object with the same name.

How would you create and implement styles into your own custom class? Thanks for you replies in advance.

12-Mar-02 15:49

I'll assume you mean styles like WS_VSCROLL and such...?

Umm...well I dunno if windows reserves all 32 bits of the DWORD nStyle paramter, but you could find out pretty easy and use bit locations that weren't used or use a DOWRD StyleEx and set your own bits using bitwise OR's.

Like this overloaded version of Create

Create(CWnd* pParent, DWORD nStyle)
{
  //Extract the bits your interested in using bitwise AND's
  //(i think) and basically do what you want to/with them before 
  //sending the rest to default Create.
  CWnd::Create(nSytle...blah);
}

For instance if bit 17 wasn't already used by CreateWindow() you could use it to specifiy SHOW/HIDE 3D borders around custom button control.

How do you handle them I guess is what I was wondering. Say you have an enumeration.

enum { ID_STYLE1 = 0, ID_STYLE2 = 1, ID_STYLE3 = 2 };
How do you handle the those styles in a function with the bitwize OR and AND ops? Thanks for the inputs in advance.

};

void SetStyle(Style style) {m_styles |= style;}

void ClearStyle(Style style) {m_styles &= ~style;}

void Dump() {printf("Style = 0x%08X\n", m_styles);}

#define CWS_3DBORDER  0x01  //First bit of DWORD style is now used by child window style (CWS)

//Create custom control window with custom style
m_wndChild.Create(this, WS_CHILD | WS_VISIBLE | CWS_3DBORDER);

//Custom control overloaded Create function
CCustom::Create(CWnd* pParent, DWORD nStyle)
{
  m_b3DBorder = nStyle & MASK;
}

//CCustom control OnPaint handler
CCustom::OnPaint()
{
  CPaintDC dc(this);
  if(m_b3DBorder)
    //Draw 3d border cuz it was specified in style flag

  //Continue with normal drawing code
}

You may have to give the and operation the once over
I dunno how accurate my attempt at masking bits is in the above...but you should figure it out easily. I did try and give a solid example of how I would use custom flags.

CPP question

alex.barylski12-Mar-02 13:01

12-Mar-02 13:01

I have created a control from scratch derived from CWnd.
The only problem I had was deriving from this control at first I couldn't figure out why nothing was happening after the overloadded Create function was called. I quickly figured out how t fix it, but i'm not 110% sure why?

Basically in my newly derived class I had to implement(???) each function that was implemented in the base class and call the base class version in the derived class.

Is there another way around this...?

Cheers!

I would be puzzled too because, generally speaking, you do not have to do this. You only need to implement functions that are overridden in derived classes or those that are pure virtual (not implemented in the base class.)

Something strange is afoot at the Circle-K.

alex.barylski12-Mar-02 15:37

12-Mar-02 15:37

I can't figure it out...i've done nothing out of the ordinary...my computer is definetly screwing up though.

default paramters in one of my member functions compiled fine, but the classwizrd wouldn't locate the function...so I had to remove one default parameter and everything worked fine again.

Thanx

Did you really have to implement every function? CWnd has an awful lot of functions.

Sorry to dissapoint you all with my lack of a witty or poignant signature.
